Abstract: An apparatus includes one or more functional circuits, a debug circuit configured to implement one or more debug features for the one or more functional circuits, and a validation circuit. The validation circuit is configured to receive a request to access debug features, and to send an identification value corresponding to the apparatus. The validation circuit is further configured to receive a certificate generated by a server computer system, the certificate including encoded debug permissions, and to decode the debug permissions using the identification value. Using the decoded debug permissions, the validation circuit is further configured to enable one or more of the debug features.
